tains to make and use the same.

This invention relates to a new and useful improvementin carburetors andit consists in the construction and arrangement of parts hereinafterdescribed and definitely pointed out in the claims.

The aim and purpose of this invention is the provision of an improvedcarburetor, having provision for retaining a constant and uniform supplyof gas, and further to construct a receiving tank or reservoir for thegas which will be automatic in its operation and simple in itsconstruction.

A still further object of the invention is to so arrange the carburetorthat an increased evaporating surface may be had in a comparativelysmall apparatus, and finally in the details of the constructionhereinafter described for rendering the apparatus exceedingly simple forgeneral use. These objects are obtained by the construction illustratedby the accompanying drawings, and in which- Figure 1 represents avertical section of the apparatus including the gasometer and Fig. 2, isa detail elevation of the out off valve.

In the drawings A represents a carburetor casing, formed with horizontaldividing walls B dividing the interior of the easing into threecompartments A A and A The upper portion of the interior of the casingis formed with an inclined partition or cap 0 inclining downward to acommon center and located a short distance from the top B therebyforming a space D.

F represents a feed tube passing through the top 13*, the partition Gandinto the chamber A.

F represents a feed tube arranged beside the feed tube F, extending intothe chamber A and F represents a feed tube entering cham ber A Thesetubes F, F have the perforations a, a a therein located at points abovethe normal height of the liquid in the compartments.

G represents a suitable wicking extendlng up from the bottom of thecompartment A through suitable opening in the edge of the partition 0and carried down the face thereof resting on vertical ribs 0 formed onthe upper face of the partition 0. The partition is also provided'at thehighest point between the ribs with suitable apertures.

Arranged across the interior of the compartments A A are supporting rods71, located at points'adjacent to the upper end or top of I thecompartments. Over these rods h is passed the wickin g H, the rods beingarranged so that the wicking will be carried up from the bottom over therods down and up unt1l it reaches the opposite side, the arrangementbeing substantiallythe same in each compartment. Instead of carrying theWlOklIlg directly down at the center it is spanned or carried over thecentral adjacent rods forming a flat surface at this point.

I represents an air supply pipe leading into the space D through the capthe same being connected with any suitable air supl in a aratus. p Lodate d within the compartments A, A A are floats K'having stems extendingup through the tubes F, F F at the top of the apparatus. The stems mayhave a series of indicating marks thereon and pass through the caps K ofthe tubes. The liquid within the compartment will force the float up,the

stems within the tubes projecting beyond the.

end thereof and indicating the height of the liquid within thecompartment.

Lis the discharge pipe having a series of branch pipes Z, Z and Zextending into the carburetor at different elevations, the pipe Zextends up into the drum N at which point it is provided with a suitablecut ofl: m of the following construction: The discharge end of the pipeL is formed with three or more apertures O and has pivoted thereon a cutofif valve 0 having three corresponding apertures registering with theapertures of the discharge end of the pipe. The valve 0 has aweightedarm 0 extending out from one edge thereof, to which a suitable chain Pis attached, the opposite end of the chain being carried up and securedto the dome of the drum. Ears 0' are formed on the opposite side of thevalve 0' which engage a suitable lug 0 on the nozzle on the pipe L. Bythis means the movement of the valve is limited.

In operation the caps of the feed tubes F, F and F are removed. Gasolineis filled into the compartments, that passing through the tubes F, Fentering the compartments A A \Vhen the compartments are filled to apoint slightly below the rods h the caps are replaced on the fillingtubes and air is forced in through the tube 1. The cock in the pipe L isthen opened and the gas allowed to pass therethrough. The wicking G, bycapillary attraction, carries the gasoline into the compartment D atwhich point it is vaporized, the contact of the air being both above andbelow the wicking, by reasons of the ribs 0 which hold the wicking abovethe partition. All drippings from the wicks G are caught and held by theupper or outer faces of the ribs, while the apertures in the partition 0allow the air to pass therethrough onto the gasoline compartments below.hen the amount of gasoline in the compartments has been reduced thecocks in the uppermost pipes are closed and the lowermost pipes openedso that the dense vapors near the surface of the gasoline in the lowercompartments will escape. By this means the density of the vapors andconsequently the richness and regularity of the gas may be retained andsupplied to the gasoineter irrespective of the quantity of the gasolinein the carburetor. By placing the wicking H in the compartments in themanner above described an increased area or surface for the gasoline, isexposed to the action of the air all of which tend to enrich or increasethe density of the gas. The perforations in the feed pipes are arrangedto admit air to the compartments A A and to allow the gas to escape whenthe lower pipes are closed. As the gas escapes through the pipe L itenters drum M, the valve 0 being normally opened by reason of theweighted arm. As the drum or hell rises carrying the chain P up theweight is lifted closing the valve shutting off the supply of gas. Bydividing the carburetor easing into two or more compartments anincreased area or exposed surface is obtained, the vapor passing up fromthe lower compartments through the 3 tube E when the pipe Z is closed.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a carburetor, the combination with the casin g, having horizontalpartitions therein dividing the interior thereof into a series ofcompartments, feeding tubes leading into the respective compartments,those for the lower compartment passing through the compartments aboveand formed with a series of perforations at points Within the uppermostcompartment, a suspended wicking above the upper compartment, wicking inthe lower compartments, extending from the bottom to the tops thereof ina series of folds orloops, an air supply pipe, at discharge pipeentering the top of the casing, a series of branch pipes leading fromthe said discharge pipe and entering respectively the respectivecompartments and a gasometer in which the discharge pipe leads,substantially as described.

2.'In a carburetor, the combination with the casing, having two or morecompartments therein arranged one above the other and having communication with each other, means for supplying the compartments with avolatile liquid an inclined perforated partition above the uppercompartment formed with openings therein, a suitable wick extending fromthe compartment below the partition up to and over the inclinedpartition, horizontal supports in the compartments near their upper endsarranged at intervals, wicking supported by said supports and extendingdown toward the bottom of the compartments, means forsupplying air tothe compartments, and a series of discharge pipes entering therespective compartments and leading into a common discharge pipe,substantially as described.

3. In a carburetor, the combination with the casing having horizontalpartitions therein dividing the interior thereof into a series ofcompartments, feeding tubes leading into the respective compartments,those for the lower compartments passing through the compartments above,and formed with a series of perforations at points within the uppermostcompartment, floats in the respective compartments having stems passingthrough and above the tubes, a suspended wicking above the uppercompartment, wicking in the lower compartments, extending from thebottom to the tops thereof in a series of folds or loops, an air supplypipe, a discharge pipe ontering the top of the casing, a series ofbranch pipes leading from the said discharge pipe and enteringrespectively the respective compartments and a gasometer in which thedischarge pipe leads, substantially as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
